Application led March 23, 1926;

This invention relates to folding combs, and has particular reference toa locking hinged joint for connecting the sections of a folding comb orother analogous article, the same being in the nature of an improvementover a similar invention set forth in my prior United States LettersPatent No. 1,579,143, granted on March 30, 1926.

in the prior patent, the locking means for retaining the comb sectionsin opened condition necessitated a separate' shiftingl operation,whereasthe present inventionV comprehends an improved lockingjoint orhinged connection for the sections of the folding comb which functionstoautomatically lock the sections in opened relation when they are si j toan opened condition, thereby elimina' j the necessity of manipulating or.flu ng locking devices as in the previous case.

More specifically, the invention comprehends a hinge connection for thecomb sec tions inv which the leaves are formed with resilient extensionsadapted when the sections are opened to overlap and requiring adeflection of the overlapping portions to swing the sections from anopened to a closed relation, whereby said sections are rigidlymaintained in an opened condition against accidental closing.

The invention furthermore comprehends in a folding comb, a lockinghinged joint or connection which is comparatively simple, yet strong anddurable in its construction and highly efficient in its purpose.

ln the drawings- Figure 1 is a fragi'nentary front view of i sectionalcomb equipped with a locking i" d joint constructed in accordance with:he invention;

Fig. 2 is a rear view thereof;

Fig. 3 is a plan view thereof illustrating the sections partiallyfolded:

Fig. l is 'a similar view illustrating the engagement thc lockingelements when deflected and immediately prior toY their inal lockingengagement;

is a similar view illustrating the comb sections fully opened with thelocking elements in fully engaged locking relation.

Referring to the drawings by characters of reference, and 11 designate,respectively, a pair of comb sections which are adapted to be connectedfor swinging movement from an end-toend alined opened relation to aSerial No.' 96,726.

side-by-side parallel or closed relation. rlhe means for connecting thesections and for locking the same in their end-to-end alined openrelation consists of a hinge including a pair of leaves 12 and 13 formedwith alined interengaging knuckles 145 at one end of each leaf, throughwhich knuckles a hinge pin 15 extends. rlhe leaves 12 and 13 arerespectively provided with an angularly bent portion 16 and an angularlybent portionY 1-7 which lie within therabbeted portions 18. of the combsections, the leaf portions 12 and 13 extending over the rabbetedconfronting ends of the comb sections 10 and 11. The angular portions 16and 1'? are,

respectively, formed with reversely bent overlying terminals 19 and 20through which rivets or other attaching devices 21 extend for securingthe same to the comb sections. The extremity 22 of the terminal 19 isoifseJ outwardly approximately the thickness of the material from whichthe terminals are formed and a portion of said extremity extends beyondthe end of the sectionY and the pivot pin 15. rlhe extremity 23 of theterminal 2O extends approximately a similar 'distance beyond the end ofits comb section and the pivot pin 15. rEhe material from which theterminals 19 and 20 and extremities 22 and 23 are formed, is resilient,and the position or arrangement of said terminals and extremities issuch that when the comb sections are swung` from a` folded relation toan opened relationthe said extremities will interengage to rigidlymaintain the sections in an opened relation, and will necessitate adeiiection or flexing of the terminals when opening or closing the combsections. In order to further augment the locking action set up by theinterengagement of the extremities 22 and 23, when the comb sections areopened to an aline'd or end-toend relation, the said extremities areformed in their confrontingY faces, respectively with a projection 24and a complementary keeper opening 25. Under this construction andarrangement, it is obvious that a locking joint or hinged connection forthe sections of folding combs has been devised which automaticallyfunctions to maintain the sections in opened relation when the same areswung to such a position, and which is automatically disengaged when thesections are swung at an angle to each other. Y

It is to be understood that within the scope of the invention thelocking terminals and their extremities may be made as a separate partfrom the hinge although preferably the same are constructed as anintegral part of the hinge leaves.

l/Vhat is claimed is:

1. A folding comb, including a plurality of hingedly connected sections,and interengaging resilient elements for retaining the sections inopened alined relation.

2. A folding comb, including a plurality of hingedly connected sections,and means for retaining the sections in opened alined relation,comprising a pair of resilient elements projecting' from the adjacentends of the sectionsV and adapted to be flexed into overlapping relationupon opening move nient of the comb sections.

3. A folding comb, including a plurality of hingedly connected sections,and means for retaining the sections in opened alined relation,comprising a pair of resilient elements projecting from the adjacentends of the sections and adapted to be flexed into overlapping relationupon opening movement of the comb sections, said elements being formedas integral extremities of the leaves of the hinged connection betweensaid comb sections.

4. A folding comb, including a plurality of hingedly connected sections,and means for retaining the sections in opened alined relation,comprising a pair of resilient elements projecting from the adjacentends of Leonesa the sections and adapted to be flexed into overlappingrelation upon opening movement of the comb sections, said overlappingelements having complementary locking means on their confronting` facesadapted to interengage when overlapped.

5. A folding comb including a plurality of sections, and. a hingedconnection therebetween permitting of the swinging oi the saine from afolded side-by-side relation to an open end-to-end relation, said hingedconnection including resilient means forming an integral part thereoiafor maintaining thee sections in opened alined relation againstaccidental closing.

6. In a folding comb including a plurali-,t of hingedly connectedsections, coact' means on said sections operable by the swinging of thesections in a plane perpendicular to the axis of the hinge into anopened alined relation for rigidly retaining said sections in the openedalined relation against accidental closing movement.

7. In a folding comb including a pluralit of i hingedly connectedsections, coactin meas on said sections operable by the swinging of thesections in a plane perpendicular to the axis of the hinge into anopened alined relation for rigidly retaining said sections in the openedalined relation against accidental closing movement, one ot said meansriding over the other to an interlocking engagement therewith.
